Peter is known for blending space opera with hard science fiction,
often combined with the bizarre. For example, his Night’s Dawn trilogy
is a space opera epic that takes a space is an ocean approach that is
pretty diamond hard on the scale, and throws in a plague of the souls of
the returning dead.

His Commonwealth Saga, on the other hand, takes the unusual approach of
an interstellar Portal Network… based on railway travel: taking a
train
from a station on one planet and arriving at a station on another.
Spaceships don’t come into play until seriously long distances need to
be covered. Oh, and then there’s the unstoppable galactic-scale Alien
Invasion taking out dozens of star systems at a time.

The Void Trilogy is the latest series, taking place in the same
continuity as the Commonwealth Saga, thousands of years later. The black
hole at the center of the Milky Way is discovered to be an “artificial
universe”, the Void, that is gradually consuming the galaxy to fuel the
outlandish mind over matter powers of its denizens. A major religious
cult in the Commonwealth decides to pilgrimage into the Void, an action
which might trigger an expansion that could destroy the galaxy. Oh, and
The Messiah can dream the life of Edeard, one of the humans that lived
in the Void hundreds of years prior, and his sharing of these dreams are
the foundation of his cult.

Be warned, though: almost everything he writes is a door stopper space
opera with loads and loads of characters, and in recent years this has
only gotten more pronounced. It is also worth noting that almost
everything he has written has been extremely well
received.
